IMPROVEMENT IN MACHINE CARD-TEETH.

' To all whom t may concern,.-

Be itknown that I, WILLIAM MONTGOMERY, ot' Roxbury, in the `county ofNorfolk and State of Massachusetts, have :invented` a new and ImprovedMode of Making Filleting or Cards for Carding Wool; and I do herebydeclare that the same is fully described and represented in thefollowing specification and the accompanying drawings, letters, ligures,and references thereof. I

In the said drawings, Figure l denotes a side View of a piece of myimproved filleting. Fig. 2 is a cross-section ot' the same. Fig. 3 is afront View of one of the improved iilletplates. Fig. 4 is a side view,and Fig. 5 a top View, of the same.

In the manufacture of iilleting or cards for carding Wool or otherfibrous material it has been customary to manufacture them of bent wires4inserted through leather.

Instead of making the teeth of round wire in the manner as heretofore,my improved method consists in forming them from a plate or sheet ofmetal cut and bent into the form of two triangles united to and standingwith their planes at right angles to a rectangle.

In Figs. 3, 4, and 5 the two triangularteeth are seen at a b as arrangedparallel to one another and standing with their planes perpendicular toa rectangular or base part c. Now, it is not necessary that these teethshould be precisely triangular, as they may bear approximately to suchform nor is it necessary that the base to which they are united shouldbe rectangular, as it may be made square. Teeth thus formed are to belinserted through a strip of leather or other suitable flexible materialin asimilar manner to which the common card-teeth are inserted, thebroad plate base part of each tooth being brought close up against theunder side ot' the. same, as seen in Figs. l and 2.

When card-teeth are made simply of Wire, the base of such teeth aii'ordslittle or no support to them, it operating principally to prevent themfrom being drawn out of the leather while the card is in operation.

The broad base of my improved teeth resting on the substance or surfaceto which the iilletin g is fastened, and also against the sheet ofleather through which the teeth are passed, forms a strong support forthe teeth not only against longitudinal but against lateral strainbrought to bear upon them; besides, giving to each tooth a triangularform, or making it of a sheet of metal, imparts to it great strength andrenders it particularly useful in carding coarse material.

I would remark that I do not claim to make card-teeth of wire; but vthat I do claim as my invention is- The making of each two teeth and thebase thereof of a metallic plate formed and bent Asubstantially in themanner as hereinbefore described.

In testimony whereof I `have hereunto set my signature this 5th day ofDecember, A. D. 1853.

V. MONTGOMERY.
